Two Families of Sequence Pairs With Zero Correlation Zone

摘要

A family of sequences with zero correlation zone,which is shortly called ZCZ set, can provide CDMA systems without co-channel interference nor influence of multipath. This paper presents two types of ZCZ sets of non-binary sequence pairs, which achieve the upper bound of family size for length and zero correlation zone. One,which is produced by use of a perfect complementary pair and an orthogonal code, can change zero correlation zone,while the upper bound is kept. The other, which is generated by use of a newly defined orthogonal pair and an orthogonal code, can offer such CDMA system as a binary ZCZ set is used.
